Liquid toners comprising amphipathic copolymeric binder having insoluble components in the shell portion thereof

The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The S material portion comprises at least one soluble component and at least one insoluble component, wherein the insoluble component is the reaction product of monomers having an absolute difference in Hildebrand solubility parameter from the liquid carrier of about 3.0 MPa1/2 or greater. These toner particles can exhibit excellent final image durability characteristics, and can also provide toner compositions that provide excellent images at low fusion temperatures on a final image receptor.
